There is a small error in challenge 9 where we get messed up or pass it luckily. After the first loop when we jump off and drop on the 2nd stage and continue our path to the next loop, the gap between the loop and the ramp or a kind of ramp is not made properly. The thing happens next is- the infernus front bumper strikes the initial of the loop so fast that it makes it messed up (like rolls it up and slows it down). So, i request you too kindly take a look on it and fix it up if you feel my message is right.

You're by far the first person I have seen complaining about Challenge 9. I don't find anything wrong with it, had passed it many times and never messed up like that. Everything is based on precision, timing and speed.
